Adjustable (Ground only for fixed mode)

output voltage (Ground only for Fixed-Mode).

O

2

The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤

20Ω) capacitor must be connected from this pin to ground to

insure stability.

I

3

The input pin of regulator. Typically a large storage capacitor

(0.15Ω ≤ ESR ≤ 20Ω) is connected from this pin to ground to insure

that the input voltage does not sag below the minimum dropout

voltage during the load transient response. This pin must always be

properly.
